Monitoring and validation of decentralised water and wastewater systems for increased uptake

Decentralised water and wastewater systems are being implemented to meet growing demand for municipal services either in combination with centralised systems or as standalone systems. In Australia, there has been increased investment in decentralised water and wastewater systems in response to the capacity constraints of existing centralised systems, an extended period of below average rainfall, uncertainly in traditional water sources due to potential climate change impacts, and the need to reduce the environmental impact of urban development. The implementation of decentralised water systems as a mainstream practice at different development scales is impeded by the knowledge gaps on their actual performance in a range of development types and settings. As the wide-spread uptake of these approaches in modern cities is relatively new compared to centralised approaches, there is limited information available on their planning, design, implementation, reliability and robustness. This paper presents a number of case studies where monitoring studies are under way to validate the performance of decentralised water and wastewater systems. The results from these case studies show the yield and reliability of these decentralised systems, as well as the associated energy demand and ecological footprint. The outputs from these case studies, and other monitoring studies, are important in improving decentralised system design guidelines and developing industry wide management norms for the operation and maintenance of decentralised systems.

AbstractThe implementation of dual reticulation systems for returning recycled water to the home for nonpotable use is now common in new Australian housing developments. Managing the associated public health risk requires consideration of the potential for crossconnections between recycled and potable water pipes. While current protocols for detection exist, they are time consuming and cross-connections have occurred despite their implementation. Cross-connections may occur anywhere from a network to single...

After years of investment and construction, in some relatively developed areas, the stage of large-scale investment in infrastructure has basically been completed. However, China is still in the stage of rapid development of industrialization and urbanization, and infrastructure, such as transportation, water conservancy, energy, information, and pipe networks, remains. There are many shortcomings, and the problem of inadequate development imbalance is still quite prominent.

Allowing stormwater to recharge groundwater may help solve urban water problems
The Indonesian capital of Jakarta is a dramatic example of some increasingly common water problems because it faces a triple threat:
The sea level is rising from climate change.
The city is sinking due to low aquifer water levels from overuse.
Impervious concrete covers so much ground that the rain can no longer recharge the aquifer.
Rain that could keep wells from running dry and stop Jakarta from sinking instead flows over...
